Abstract

The present invention provides a pneumatic cylinder. It has one cylinder inserted internally with a rod body, which one end is connected with the piston and the other end stretches outward from the cylinder body. The inner space of the cylinder is divided by the piston into two chambers, which exchange the inner gas with each other through valve operation. The piston moves when the valve is opened and stops while the valve is closed. When the piston start to move against the sliding sleeve of the piston wedges, the valve in steadily opening, then the regulated spring on the other chamber pushes the piston towards the opposite direction.

As shown in FIG. 2, the other end of the rod body 30 is outside the stop boring body 21, and is provided with a locking portion 32, and the lock body (such as a cabinet door panel or a trunk lid of the car) is fixed to Another object (cabinet side panel or car luggage ~ the two objects are far apart from each other, so that the rod body 3〇 is pulled = extension IMII Em Page 8 1281008

One of the pistons 60 in the direction of the ring 21 of the cylinder 21 is stopped by the distance of the present invention, and the second air chamber 23 is brought to the equilibrium state, and the piston of the invention is placed on the same side. And when the stop is in the hair, the plug 60 is facing the outside, the live movement makes the gas valve 6 4, and one of the technical special time, please refer to the gas valve 64 formed separately toward the room so that the piston makes the The technical feature of the two objects is the state of the stop collar. One of the squares of the valve seat 40 is provided with a first air groove 61, and the inner diameter of the three air grooves 63 is larger than the first gas. 61, 6, 2, 6 3 are mutually conductive inner diameters larger than this, and the rod body 3 is also held, and the gas in the first gas chamber 22 can flow into the second gas chamber 23 through the stop shaft. When the two objects are apart from each other as shown in FIG. 2, the air pressure piston 60 of the second air chamber 23 is fitted, so that the first air chamber 22 and a sealed space make the piston 60 stand still at 60. Any position that can be fixed in the cylinder 21 can be maintained at an appropriate distance for a long time. However, the two objects are moved away from each other, so that the pistons 60 can move along the cylinders 2, so that the two objects move closer together. . For example, please refer to the second and third gas grooves 62 and the third gas groove 63, which are shown in the second and third sides of the piston. The inner diameter, the inner diameter of the second gas groove 6 2 groove 6 1 , the first, second and third gas grooves refer to the third gas groove 63 facing the first gas groove 61 One end to the other end of the third air groove 63, a sliding sleeve spring 1 and a sliding sleeve 70 are sequentially accommodated, and the outer edge of the sliding sleeve 70 is opposite to the inner edge of the third air groove 63. The sliding sleeve 70 is disposed at one end of the first air groove 61 with a plurality of second passages 72, and the sliding sleeve 70 is provided with a sliding sleeve groove 73 at the other end, and the sliding sleeve groove 73 is

In addition, as shown in the figures 2, 3, 6 and 7, the first air chamber 22 and the second air chamber are in a state in which the check valve 44 protrudes out of the limit sleeve 46. The gas in 2 3 changes in an equal proportion, and when the sliding sleeve 7 〇 and the second positioning portion 65 are engaged with each other, the adjusting spring 24 can push the piston 60 toward the check valve seat 40 The first spacer 640 1 is pushed by the check valve 44 when the first spacer 640 1 of the piston 6 and the latching portion 44 〇 1 of the check valve 44 are engaged with each other. The first air groove 61 is closed, and the second spacer 6402 is driven to push the sliding sleeve 7 to release the locking state between the sliding sleeve 7θ and the second positioning portion 65 to drive the sliding sleeve 7〇. Towards the set/tube

1281008 V. INSTRUCTION DESCRIPTION (15) The direction of movement of 3 1 gradually pushes the gas of the fitting portion 4402 and the chamber 23 to the gas no-pass 4702, and in the seat, finally, the check valve seat 40 is operated before the original Please > has a ball plug 4101 (Throttling is used to adjust the ball 41 0 1 to control the flow of the gas, • the plug 4101 can be in the free throttling groove 41, the check valve seat 4 is outside), and When the 41 0 1 is closed to the throttle, and the second example. In the present invention, at the same time, the piston 60 is pushed by the adjusting spring 24, and the check valve 44 moves in the direction of the throttle groove 41 to release the closed state between the limiting sleeves 46. The second gas method flows to the first gas chamber 22, and flows through the fifth through grooves 43 and the fourth passages 4 to the throttle groove 41. The piston 60 gradually excludes the second gas chamber 23. The gas, and the mutual engagement, causes the pneumatic cylinder 2 to return to the unstarted state. Referring to FIG. 6, the throttle groove 41 is sequentially housed and a throttle valve 41 0 2 , and the throttle valve 41 0 2 Valve, such as a needle type, a sliding type, a rotary type, etc. 0 1 in the position of the side stream slot 41, such that the ball plugs a fourth passage 4 between the throttle groove 41 and the seat groove 43. When the throttle valve 4 1 0 2 is away from the ball plug 41 When the ball throttle groove 41 is freely movable, the ground in the second air chamber 23 flows through the seat groove 43 and the fourth passage 4 2, and can pass through the throttle groove 41 again. One of the air holes 41 〇3, out of the air (ie, discharged from the air cylinder 20 (as shown in FIG. 2), the throttle valve 4 102 presses the ball plunger 4101, so that the ball is plugged into the fourth passage 42, the second gas The gas in the chamber 23 is not in the groove 41. Thus, the first gas chamber 22 (such as the gas in the gas chamber 23 in Fig. 2 can be maintained at a fixed ratio), as shown in Fig. 2, The pneumatic cylinder 2 is not in progress

Page 19 1281008 V. INSTRUCTION DESCRIPTION (16) In the state of use, the gas valve 64 is located in the cylinder 2 1 away from one end of the stop collar 50, so that the first spacer 6 4 0 1 The card abutting portions 440 1 of the check valve 44 are mutually abutted to limit the position of the check valve 44 in the seat groove 43; 嗣 'Please refer to FIG. 8 when the rod body 3 〇 When the piston 60 is gradually moved toward the stop collar 50, the check valve 44 is gradually urged toward the cylinder 21 by the elastic restoring force of the check spring 45, so that the shoulder 4404 is configured to close the limiting hole 470 1 and each of the fifth channel 4702 (as shown in FIG. 7), so that the gas of the second gas chamber 23 gradually increases with the movement of the piston 60; When the air pressure is large to push the first air chamber, if the second air chamber pressure of the throttle spring 24 is 40, the first air two air chamber 23 is fixed to the cylinder, and the same air chamber 22 is moved in the direction of the reference. The gas is activated, and the gas is closed by the closure, and the gas is sealed by the gas chamber 22 of the second and the second sealable ring 50. The first spacer 6401 of the first air chamber 22 causes the first spacer 6401 to be driven by the gas of the opening 22 to the second air chamber 23; the rod 30 stops. Moving, as shown in Fig. 9, the elastic restoring force generated will push the piston 6 to move in the direction of the piston, so that the gas of the second gas chamber 23 is pressed by the gas pressure greater than the first gas chamber 22 (e.g. The gas of the second gas chamber 23 in Fig. 2 pushes the first separator, and the groove 6 1 (as shown in Fig. 3) causes the gas between the first gas chambers to no longer flow, so that the piston 6 〇 Any position in the body 21. As shown in Fig. 2, when the piston 6 〇 is facing the stop shaft, the gas of the first air chamber 22 is pressed again.
